Be it known that I, RAY G. ldrnns, a

citizen of theUnited States, residing at 1 Canal ulton, in the county of Stark and State of Ohio, haveinvented a new and use-j U ful Door Opener, of which the following is a specification. Q j r t This invention relates to door opening mechanism for use upon garage doors and thelike and has special reference operating door opener.

The objects of the invention are to provide a distributing valve in a fluid pressure line which may be" easily and quickly oper ated to allow fluid pressure to enter either end of a cylinder throughwhich a garage a door or doors may be opened or closed.

Other objects are the provisionot a device w th of this character which will be extremely i easily and readily operated.

simple in construction andwhichlmay be p Withthese objects in view the invention consists in the novel construction and arr rangement of parts, hereinafter described .jparticularly pointed out in the appended claimsyjit being understood that various {tchanges in the form,jproportions, size and minor details of construction maybe made illustratedin accompanying drawings, and

Within the scope of theappended claims, withoutdepartingfrom the spirit orsacrificin any of the advantages of the invention.

fihe invention thus setforth in general 1 terms is illustrated in the accompanying drawings formingv part hereof, in which- Figure l is a. side elevation of a portion of the wall of a garage or similar building showing the improved door opening apparatus embodying the invention applied thereto; and j r r j r Fig. 2, asectional view through the valve showing portions of the distributing mechanism. r i n A practical embodiment of the invention is disclosed in the accompanying drawings, formingapart of this specification in which similar numerals of reference indicate corresponding parts throughout the several A I to views. a l a Although it will be understood that the invention may be applied in various forms vthe construction shown in the accompanying drawingsis chosen for the purpose of illusi tration. Referringto this construction the numeral 1 indicates generally the portion of a wall of a garage or similar building and the numerals 2 and 3, a pair of sliding doors of any well known construction mounted upon a track 1 in the ordinary manner. 1

A cylinder 5 of a length substantially equal to the width or the two doors is fixedly: mounted upon the door 3 by means ofb'rack ets or straps 6, a piston 7 being provided within said cylinder the rod 8 thereof being connected as shown at 9 to the door 2.

SA. U-shaped bracket 10 is supported upon the wall 1 in a suitable position above the door 3 and supports a pair of nozzles or jets 11 and'12', the inner extremities of which entend within the bracket upon oppositesides thereof. A stop cock 1301 the like isprovided in each of the jets for the purpose of regulating the amount of air or other fluid which may bepassed' therethrough, The jet 11 is connected by means of a iiexible hose 1d withthe forward end of the cylinder 5,

at 15, and the jet 12 is connected by means ota similar hose 16 wlth the rear end of the cylinder as shown at 17.

A feed pipe 18 extends from asuitable source of compressed air or otherfluid and is providedwitha depending, slightlyfiexible pipe 19upon the lower end of which is supporteda double'valve casing indicated generally by thenuineral 20, said valve casmg being suspended within the bracket 10;

and between the jets 11 and 12.

[A lever 21 is pivoted intermediate its extremities as shown at 22, upon thebracket 10, theupper end of said end having an elongated eye 23 which receives a stud 24: upon the valve casing 20. Cords or other flexible members 25 and 26 are connected to the lower extremity of the lever 21 and disposed in opposite directions, the cord 26 passing over a pulley 27, both or these ends returning to any suitable portion of the garagei'rom which it is desired to operate the 1 doors.

each valve, normally holding said valve in the closed position.

Each of the valves 31 is provided with a longitudinal bore extending through the outer end thereof and communicating at the inner end with a transverse bore 36 located through the reduced neck oi the valve. Normally the fluid pressure within the chamber 29 will hold each of the valves 31 in the closed position.

When it is desired to operate the mechanism to open the doors the lever 21 is rocked by means of the cord 25 moving the valve casingtoward the jet 12, the adjacent valve 31 being engaged by said jet and forced inwardly allowing fluid pressure to pass from the pipe 19 through said valve and into the jet 12 and then through the hose 16 to the rear end of the cylinder forcing the piston outwardly and opening the doors.

In order to close the doors the cord 26 is pulled, moving the valve casing toward either of the jets which communicate with opposite ends of the cylinder the fluid operated mechanism may be very simply operated.

Although a lever is shown for moving the valve casing into engagementwith the jets, it will be understood that any usual and well known means may be provided for shifting the valve casing into engagement With either of the jets and for normally holding the valve casing in the neutral position. It will also be understood that the device may be applied to a single door as well as to double doors, or to hinged doors as well as to sliding doors, without necessitating any change in the valve shifting mechanism.

I claim:

1. A door operating mechanism of the character described comprising in combination with a fluid cylinder, a jet communicating with each end of said cylinder, a fluid supply line, a valve casing therein, a pair of normally closed valves within said casing,

each valve being arranged to be opened by engagement with the adjacent jet and means for moving the valve casing toward either jet to allow lluid from the supply line to pass through said valve and jet to the adjacent end of the cylinder while the other valve remains closed.

2. A door operating mechanism of the character described comprising in combination with a fluid cylinder, a pair of spaced, fixed jets communicating with opposite extremities of said cylinder, a fluid supply line, a valve casing connected to said fluid supply line and suspended between said jets and normally located out of engagement with both jets, a pair of normally closed valves within said casing, each valve being arranged to be opened by engagement with the adjacent jet, while the other valve remains closed, and means for selectively moving said valve easing into engagement with either jet to allow fluid from said supply line to pass into the adjacent end of the cylinder.

In testimony that I claim the above, I have hereunto subscribed my name.
